Intentando crear un entorno virtual de Python pero obteniendo OSError

He instalado python3.3, pip-1.5, ditribute-0.7.3, virtualenv-1.11.

Estoy dando el siguiente comando para crear un entorno virtual

virtualenv --no-site-packages test

Estoy teniendo el siguiente error

name@server:~/py_virenv$ virtualenv --no-site-packages test

Por favor, ayúdame a resolver esto.

Esto se debe a un error en las herramientas de configuración . Se ha solucionado en v2.1.

De lo contrario, la solución es instalar el último virtualenv (1.11) usando pip, o usar virtualenv 1.10.1:

Primero, desinstale virtualenv:

pip uninstall virtualenv

Es posible que deba ejecutar esto dos veces (por alguna razón desconocida) para desinstalarlo realmente. Luego instale usando pip o easy_install:

pip install virtualenv

o

easy_install "virtualenv<1.11"

Es posible que necesite sudo para ejecutar estos comandos.
